APPARATUS FOR DISPENSING AND DRAWING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 297,221., dated April 22, 1884.

Application filed June 12, 1883. (Nomodeh) H To all whom it may concern:

Be it known that I, LoUIs BERGEN, of New York, in the county and State of New York, have invented a certain. new and useful I'mprovement in Apparatus for Drawing and Dispensing Liquids, of which the following is a specification.

This improvement relates to draft or dispensing apparatus for effervescent or foaming liquids.

The improvement consists in the combination, in such an apparatus, of two vessels or compartments, pipes leading to the two ves sels or compartments from a receptacle containing the liquid, a pipe or passage establishing communication between the two vessels or compartments, a valve controlling the pipe or passage just named, and vents or gasescapes in the upper part of the two vessels or compartments whereby liquid may be introduced into either of the vessels or compartments, communication may be opened between this vessel or compartment and the other vessel or compartment to relieve such liquid of surplus gas, and subsequently the gas may be allowed to escape from the vessel or compartment into which it was admitted.

The accompanying drawing represents a central vertical section of an apparatus embodying my improvement.

A A designate two vessels, which may be of cylindrical form and made of enameled cast-iron. They have covers a a, which may be made of the same material, and are shown as secured in place by means of bolts 12, hinged to the exterior of the vessels, and adapted to fitin slots in the edges of the covers, in conjunction with nuts applied above the covers.

B designatesa pipe leading from a barrel or other receptacle containing the liquid to be dispensed, and B B designate branch pipes extending from the pipe B to the bottoms of the vessels A A These pipes B B B may be coupledor united in any suitable manner, and the pipes B B may be connected by couplings to nipples extending from the vessels A A They are provided at some distance below the vessels with cocks B B.

D D designate pipes coupled or otherwise united to the pipes B B between the cooks B B andthe vessels A A These pipes D D extend outside the vessels A A-' to a point considerably above the bottoms thereof. They are provided near the ends with cocks or faucets D D";

O designates a pipe extending between the vessels A A and connected thereto by couplings or otherwise. This pipe is provided with a cock, 0. All the pipes may be tinlined lead pipes, or they may be of any other suitable material.

t E E are vents or gas-escapes arranged on the tops of the vessels A A and consisting of suitable cocks. Obviously, a single vessel having two compartments could be used in lieu of the two vessels and a passage extending between such compartments might be used in lieu of the pipe 0, a suitable valve being provided to control such passage, \Vhen the apparatus is out of use, all its cocks are closed.

To use the apparatus,one of the cocks B or B" is openedfor instance, the cock B. Then the liquid rises by its pressure, or is raised by a pump into the vessel A. It fills the vessel as far as it can, the height to which it rises in the vessel being dependent on the pressure of the liquid when it enters the vessel. The cock B is then closed,and the cock 0 is opened to allow the surplus gas to pass from the vessel A, into the vessel A The cocks of the vents or gas-escapes E E may now be opened so as to allow the gas to escape from the was sel Aand to prevent the forming of a vacuum in the vessel A, when the cock D of the pipe D is opened. The cocks O and E may be closed as soon as the cock E is .opened. After the cock D is opened the liquid will flow from the vessel A through the said pipe D into any vessel which may be properly placed to receive it. Owing to the height to which the pipes D D extend above the bottom of the vessels, a quantity of liquid will remain in the vessel. After the desired amount of liquid is drawn from the vessel the cock D of the pipe D and the vent cock E are closed. As soon as the cooks G and 13 are closed the cock B of the pipe B may be opened to allow liquid to enter the vessel A", and immediately after the cooks D and E are closed the cock B may be closed to cut off ICO the supply of liquid, and the cock 0 may be opened to permit surplus gas to escape from the vessel A into the vessel A. After this the cocks O and E may be closed and the cocks E and D" opened to permit the liquid to escape from the vessel A". A quantity of liquid will remain in the vessel A because of the height to which the pipe D extends above its bottom. It will thus be seen that both vessels may be used at the same time, as liquid can be raised into either while liquid is being discharged from the other. This feature is important, as it enables liquid to be drawn with greater rapidity from the ap paratus than otherwise it could be drawn from the same. \Vhere the liquid to be drawn or dispensed is very highly charged with gas, the surplus gas may be allowed to escape from one vessel containing it by opening the cock 0; then the cock 0 may be closed and the vent of the vessel which received the gas may be opened to permit'the escape of the gas, and this operation may be repeated several times before the liquid is allowed to escape from the vessel containing it.

This apparatus is admirably adapted for drawing or dispensing ales and other malt liquors.

That I claim as my invention, and desire to secure by Letters Patent, is

1. In an apparatus for drawing or dispensing liquids, the combination of two vessels or compartments, pipes leading to the vessels or compartments from a receptacle containing" the liquid, apipe or passage establishing communication between the two vessels or compartments, and provided with a valve or cock, and vents or gasescapes in the upper part of the vessels or compartments, substantially as specified.

2. In an apparatus for drawing or dispensing liquids, the combination of the vessels A A pipes B B, provided with cocks B 13*, the pipe 0, provided with the cock 6, the pipes DD, provided with cocks or faucets D D, and the vents or gas-escapes E E", substantially as specified.

LOUIS BERGEN.
